# Sovereign Gateway API Summary: The Sovereign Gateway API is the interface between the Contour Runtime and the modular financial rails. It handles the authorization of paid intents, management of session-based gas tanks, and settlement of credits for publishers. Status: Gateway API Reference Topics: - POST /authorize contract - Session Gas Tank management - Publisher payout flows - Checkout session lifecycle Packages: - tdm-sdk Commands: - tdm connect - tdm fuel - tdm stats
The Sovereign Gateway provides a unified HTTP contract for agent settlement. It decouples the Contour Runtime from specific blockchain rails like Solana or Base.

When an agent issues a paid intent, the Contour Runtime sends a request to this endpoint to verify funding and authorize the transaction.
Manage prepaid balances for specific agent sessions. Gas tanks enable seamless, high-frequency micro-payments without individual wallet signatures.
Publishers can query their accumulated credits and request settlement to their configured sovereign wallets.
